BLAnEsHAnrniiiue DEVICE.

Application filed December ,To all whom it may concern:

Be it known that I, VICTOR GABRIELE,

a subject of the King of Italy, residing at 7 provision of a simple,inexpensive and easily operated device through the medium of whichsafety razor blades may be expeditiously and efliciently honed orstropped so that increased service can be obtained from eachblade,thereby'obviating the waste due to the discarding of a safety razorblade after the same has been used a couple of times.

To the attainment of the foregoing, the invention consists in theimprovement as hereinafter described and definitely claimed.

In the accompanying drawings, forming part of this specification Figure1 is an elevation showing one side of my novel device.

Figure 2 is an elevation showing the opposite side of the device.

Figure 3 is a top plan of the device.

Figure 1 is an end View of the device.

Figure is a detail transverse section hereinafter explicitly referredto.

Similar numerals of reference designate corresponding parts in all ofthe views of priate metal. To the said plate 1 is fixedly connected ahandle 2, the connection being preferably effected by threading areduced end of the handle 2 into the plate 1 as illustrated.

An appropriate honing stone 3 is arranged above and disposed at an acuteangle to the plate 1, and it will be noted that the plate 1 is providedat one of its side edges and at its ends with standards 4;; also, thatconnected by screws 5 or other appropriate means to the standards 4 is aslotted rail 6, i. e., a rail having longitudinal portions inparallelism and also having a space between the said longitudinalportions. A bolt 7 is extended loosely through an aperture in the plate1 and is appropriately fixed to the stone 3 so as not to protrude abovethe surface of the said stone. Said bolt 7 is threaded for theengagement of a nut 8 disposed 9, 1922. "Serial No. 605,904.

below the plate'l, and mounted on the bolt 7 and interposed between theplate 1 and the stone 3 is a coiled spring 9 which opcrates toyieldingly supportthe comparatively high end portion of the stone 3 soas to contribute to the blade sharpening capacity of the stone. Thecomparatively low portion of the stone is appropriately connected at thepo nt 10 to the plate 1, and at said point a rubber washer 11 isinterposed between the plate and the stone, the said washer 11 beingpreferablyretained in position by'the bolt or rivet used at the pointmentioned in connectingthe stone to the plate 1. Manifestly by adjustingthe nut 8, the user is enabled to depress or raise one end of the stoneto regulate the stone for use in conjunction with safety razor blades ofdifferent kinds.

Associated with the rail 6 is a carriage 12, on which is a handle 13 toenable the operator to conveniently move the said carriage lengthwise ofthe rail. The said carriage 12 is equipped with a roller 14 inengagement with the rail to render easy the movement of the carriage inopposite d rections on the rail.

a set screw 16 in the manner illustrated so that it can be removed togive place to other holders, with the result that the honing device isadapted to hone safety razor blades of all kinds.

As best shown in F gure 5 the roller 14 is fiXedona shaft 17 one end ofwhich is adapted to be socketed in the tubular shank of the blade holderand to be engaged by the set screw 16. On the outer end of the shaft 17is fixed a spur gear 18.

In the practical use of my novel device the safety razor blade isdisposed in the holder 15, and the holder is moved through the medium ofthe means described relative to the stone 3 when the blade will beexpeditiously and thoroughly honed, the blade be ng turned at the end ofeach traverse. The inclination of the stone or hone 3 to the plate 1 andthe rail 6 assures gradual increase of pressure of the stone against theblade when the blade is moved lengthwise of the stone in one direction,and gradual lessening of said pressure when the blade is moved in theopposite direction.

When the device is to be used for stropping purposes, a strop (notshown) is arranged lengthwise above the stone 3, and the At 15 is asafety blade holder which is detachably connected preferably by bladeholder is transferred from the shaft 17 to an upper shaft 19 in thecarriage 12, said shaft 19 having a gear 20 meshed with the gear 18 thatthe blade in the holder will be properly disposed for stropping purposesand will be reversed incident to its traverses on the strop. Manifestlywhen desired the shaft 19 can be removable.

Notwithstanding the practical advantages of my novel device it will benoted that the same is simple and inexpensive in construction andembodies no delicate parts such as are likely to get out of order aftera shortperiod of use.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a full. clear and exactunderstanding of the said embodiment. I do not desire, however, to beunderstood as confining myself to the specific construction and relativearrangement of parts inasmuch as in the future practice of the inventionvarious changes and modifications may be made such as fall within thescope of my invention as defined in my appended claim.

Having described my invention, what I claim and desire to secure byLetters-Patent is A device for honingsafety razor blades comprising aplate bearing a handle, a honing stone connected with andyieldinglysupported on the plate at an angle thereto, a rail carried by the plate.a handle movable relative to and associated with the rail, and a bladeholder connected with the handle; the said connection including a rollerin engagement with the raiL and a shaft carrying the roller and equippedat its outer end with a spur gear and adapted at its inner end for thedetachable fixture of the blade holder, and a second shaft in the handleand having a sour gear at its outer end and its inner end adapted to beconnected to the holder.

In testimony whereof I aflix my signature.

VICTOR GABRIELE.
